Sequence in situ Rolonies via in situ Slide PCR[edit]
- Purpose: Sequence the rolonies in situ to quantify the contributions of each probe to the decoded rolonies
- ie gene GNG4 has many rolonies but are they due to a single highly efficient probe or a number of different probes
- Primer design and general method: Matt:LabNotes/2015-3-14
Protocol[edit]
- Samples:
- Exp: BA8 CA12k_Nov2014_V4 Captured Rolonies
- NegCtrl: BA8 1st (cDNA) Rolonies (from old FISSEQ protocol)
Strip hybridized dye-probes with 80% formamide pre-heated to 80C[edit]
- The tissue is on thin cover-slip placed on a glass slide
- Take cover-slip off glass slide and put in small culture dish
- Incubate for 15min at RT and then wash twice with 1X PBS

Slide PCR[edit]
- Make PCR Reaction Mix on ice
Components | Volume | 2X Volume |
100uM SeqRolony_CL_Amplify | 1 | 2 |
2X Taq Master Mix | 50 | 100 |
H2O | 49 | 98 |
Total | 100 | 200 |
- Place cover-slip on clean glass slide (tissue face up)
- Use silicon isolator with circular opening to seal tissue
- NegCtrl silicon had large gaps so used glue to glue all around the circle on bottom of silicon
File:033115 SeqRolony NegCtrl.JPG
- Exp had very small leak so used glue to seal the edges of silicon
File:033115 SeqRolony ExpBefore.JPG
- Add 100ul PCR mix and seal with plastic to prevent evaporation
File:033115 SeqRolony ExpAfter.JPG
- Put on thermocycler with slide adapter
Program 90C 3min -> (90C 20sec -> 58C 30sec -> 68C 45sec) x 20 -> 68C 2min -> 15C hold
- Remove plastic seal and pipette solution into PCR tubes
File:033115 SeqRolony ExpExtract.JPG
- NegCtrl had ~90ul (good) but Exp was completely dry (bad, probably leaked out as evidenced by white haze on glass slide outside of silicon)
- Add 100ul H2O, let sit for 5min, and pipette into empty PCR tubes (to get more amplicon)
- Final amount: 190ul NegCtrl and 100ul Exp
Add Sequencing Adapters[edit]
- Qiagen PCR purification
- Elute 40ul
- Nanodrop ssDNA:
- Exp: 0.6 ng/ul
- NegCtrl: 2.2 ng/ul

Gel Check[edit]
- TBE Gel with 4ul sample + 4ul 6X Loading Dye
- 0.5ul Low Mass Ladder
